Audio Rack Selection

Bh, the rack is not as important as the floor it is on. The only sensitive item is the turntable. Regardless of what the mythology says the other components could care less what they are in or on.
To test your floor put an end table or small cabinet where you plan to put your rack. Place a 1/2 filled large glass of water on the table and walk around watching the water. You can also try jumping up and down to see what happens. If the water starts wiggling you have a problem. The solutions would be a wall shelf for the turntable or a well tunes suspended turntable like an SME, SOTA or Basis. 
It is better to keep your mono blocks behind the speakers with short speaker wires and long signal wires even if you do not have balanced connections.
After all this buy the rack you can afford that looks the nicest to you.

buy the rack you can afford that looks the nicest to you.

And then buy BDR Cones for everything.
At the price range you are in BDR Shelf and Round Things make sense too. 

Are you sure you don't want to put the monoblocks on individual amp stands (that sit directly on the floor) rather than all-in on the rack?

The taller the rack the more it will amplify seismic type vibration, you know, just like high rises and skyscrapers do. One approach is to isolate the components on their shelves with small one inch springs like you know who sells.

Mike, thank you for the idea about wall mounting the turntable. I do live on the second floor and there was quite a bit of movement when I conducted your test.

I will check out the Core products and BDR.

Are there any other quality racks out there at better price points? I still need to purchase cables and speakers. Looking to save where possible without compromising the system.
